The vaccine has been raising questions around the world and now in Canada.
The provinces have agreed they will not give the AstraZeneca version to people 55 and under.
There is a concern about blood clots forming.
Health Canada officials are warning anyone who has received that particular vaccine to look for symptoms like shortness of breath chest pains and swelling in the legs.
Staying with the AstraZeneca version, a new Leger poll shows it’s well below its competitors when it comes to trust in Canada.
While 82 per cent trust the Phizer version for themselves or family and 77 per cent are on board with Moderna, only 53 per cent feel the same way about AstraZeneca.
